Cowa Thermal Solutions AG

Cowa Thermal Solutions AG, founded in 2019 as a spin-off of the Lucerne University of Applied Sciences and Arts, is an innovative sustainability startup specializing in the development of revolutionary thermal energy storage systems for the building sector.

Cowa develops and offers compact thermal storage and phase change materials (PCM) that are specifically designed to make heating systems more compact, efficient, and durable. The Cowa COMPACT Cells are standardized solutions available in various configurations, providing maximum storage capacity in a small space. This technology is based on salt-based PCM, which are non-toxic, non-flammable, and recyclable. The Cowa-Caps increase the storage capacity of conventional water-based thermal storage by up to four times, allowing excess photovoltaic electricity to be efficiently stored as heat and doubling the heating self-sufficiency of buildings[2][4].

The mission of Cowa Thermal Solutions is to drive the energy transition by developing innovative, environmentally friendly energy storage solutions. The company relies on the best employees and partners and creates modern, flexible, and respectful working conditions. Driven by facts, Cowa strives for the highest performance, both in products and among employees. The focus is on creating sustainable energy storage systems that are essential for the success of the energy transition[2][3].

Cowa Thermal Solutions is strongly committed to the decarbonization of the building stock, both in Switzerland and worldwide. The developed thermal storage systems are not only space-saving and cost-efficient but also environmentally friendly. The PCM technology allows energy to be stored for over 20 years without capacity loss, and the materials are recyclable and non-toxic. By integrating into existing heating systems and utilizing heat pumps and photovoltaic systems, Cowa helps improve the CO2 balance of buildings and reduce dependence on external energy suppliers[2][4].

Cowa works closely with partners from the building technology sector to bring its technologies to market. The company has already successfully completed several funding rounds, including a recent round in 2024, which enables the expansion of production capacities and the consolidation of distribution channels. This support from existing and new private investors underscores the confidence in the innovative and forward-looking work of Cowa Thermal Solutions[5].

With its commitment to sustainability and innovation, Cowa Thermal Solutions positions itself as a leading company in the development of thermal energy storage and significantly contributes to combating climate change.
